Odysee was never acquired by google to my knowledge, but I could be wrong. Odysee used to be LBRY but rebranded a year or two ago.

The ! is really useful when you forget you need to run the command with sudo. sudo !!

I had a lot of trouble setting up nextcloud in the past but if you go with the Docker method, it’s really easy.

Odysee is probably the biggest one, with a lot of creators having their youtube synced with it. Peertube is also an option, but I’ve never used it.
